SPECIFICATION forming part of Letters Patent No. 737,314, dated August 25, 1903.

Application led November 3,1902. Serial No. 129.870. (No model.)v

T all whom it may concern:

yBe it known that we, CHARLES J. CARNEY, residing at Dunkirk, in the county of Chautauqua and State of'New York, and JOHN C. GORTON, residing at Cleveland, in the county of Cuyahoga, in the State of Ohio, citizens of the United States, have jointly invented certain new and useful'Improvements in Riveting Mechanism; and we do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to the letters of reference marked thereon, forming part of this specification.

This invention relates to riveting mechanism, and particularly to hinged-j aw mechanism for supporting an anvil and pneumatic hammer operating in opposition to each other and adapted to span and be clamped against the sides of boiler hre-boxes and structures of similar character for riveting stay-bolts or rivets therein. To this end we construct a pair of jaws which are hinged together at one end and are provided with an anvil on the end of one jaw and mechanism for supporting a pneumatic hammer on the end of the other jaw, and between the jaws, adjacent vto the pivotal junction thereof, we provide mechanism for drawing the free ends ofthe jaws together, so that the jaws are adapted to span and be clamped against the sides of a structure which it is desired to rivet together. These and other features of our invention are hereinafter fully set forth and described in this specification, and illustrated in the' accompanying drawings, in which; n

Figure 1 is a side View, in elevation, of mechism embodying our invention clamped upon a section of a boiler hre-box. Fig. 2 is an edgewise view, in elevation, of the same without the section of the boiler hre-box. Fig. 3 is an enlarged detail, partially in section, of the pneumatic hammer-supporting mechanism of our device. l.

In the drawings illustrating our invention, A and B are jaws having their upper portions curved toward each other until they meet and are pivoted together by means of a pivot a, upon which pivot there is also a clevis b for suspending the structure vertically. There are also clevises a and b on the jaws A and B for suspending the structurehorizontally,l

when desired. On the lowerfend of the jaw A we secure an anvil C and on the lower end of the jaw'B we forma yoke D, the lower'ends cl d of the arms of which-are adapted to be clamped against the side of a boiler fire-box- E or other structure to be riveted in opposition to the anvil C, contacting with the op-v posite end thereof.. In the ends of said arms d d and the apex of the yoke D we make sock- Y ets 0l', d', and d2, adapted to receive rods F, having spherical or semispherical heads f, op-

joints therewith, as illustrated in Fig. 3. The opposite or outer ends of these bolts F pass through socket-shaped openings hin the arms h', which project radially from a sleeve H and are provided with semispherical washers f and nuts f2, which semispherical washers operatein the socket-shaped openings h to formV balland socket .joints therewith, asv

supporting mechanism also permits the operatorto swing the sleeve H, in which the hammer I is supported laterally or to rotate it around its normal center, so as as to direct the hammer-head in any desired direction when in operation, the yokeshaped support enabling theoperator to at all times observe the operation of the hammer-head upon the stay-bolt or rivet being riveted.

Between the j awsA and B, near the pivoted junction thereof, weplace a compressed-air cylinder J, one end of which is provided with an arm J pivotedito the jaw B by means of a pivot j. In this cylinder there is the usual piston, (not showm) the piston-,rodK of which is pivoted to the jaw Aby means of a pivot 7c. From the end J 2 of the cylinder J a pipe L, a part of which is flexible, extends to an orerating in said sockets to form ball-and-socket v dinary three-way valve M, located on the jaw v B at a point where it can be conveniently operated by the hammer-operator, and from the valve M a pipe or hose extends to a suitable source of compressedairsupply. (Not shown.) By means of this mechanisnrthe jaws A B can be quickly clamped on structures to be riveted and retained thereon until it is desired to release them, which can be quickly done by means of the valve M. /Vc have thus shown and described a convenient mechanism for utilizing our invention. It is obvious, however, that parts thereof can be considerably modiied, both in construction and arrangement, without departing' from the spirit of our invention. Therefore we do not desire to confine ourselves to the exact construction hereinbefore shown and described, as,

That we claim as new, and desire to secure by Letters Patent of the United States, is l'. The combination of a pair of jaws pivoted together, an anvil on the free end of one jaw, ayoke on the free end of the other jaw, rods pivoted with ball-and-socket joints in said yoke, a sleeve, radial arms on said sleeve in which the outer ends of said rods are pivoted with ball-and-socket joints, a pneumatic hammer mounted on said sleeve, and mechanism for drawing the free ends of said jaws toward each other, substantially as set forth.

2. In a riveting mechanism, a pneumatic hammer-support, comprising.;` substantially a sleeve surrounding the rear part of the hammer-shell, radial arms on said sleeve, rods extending from said arms to a yoke on the hammersupport, and ball andsocket -joint connections between said rods and arms and hammer-support, substantially as and for thc purpose set forth.

The combination of a pair of jaws pivoted together means on said jaws for suspending them vertically or horizontally, an anvil on the end of one jaw, yoke, sleeve-androd mechanism on the end of the other jaw, a pneumatic hammer supported by said yoke, sleeve-and-rod mechanism so as to be moved laterally or radially thereon, a pneumatic cylinder between said jaws, and valve mechan,

ism for controlling the action of said cylinder, substantially as set forth.

In testimony whereof We affix our signatures in presence of two witnesses.
